Fixing Block Sigops Checking after block 478571

Although the current Re-Targeting Algorithm is fixed. The current Signature Operation checks on the proceeding blocks after the new Re-targeting algorithm (478571),
Exceed the current consensus defaults for each Block / Transaction

All transactions are considered non-standard if this fix is not assessed which will eventually cause invalidity to connection-blocks in the Mempool.

There's currently a rewrite in the primitives library that count P2SH / Legacy Sigops.
This may require a new rewrite or change in the chain file that segregates both.

Although they both must be used to calculate transaction sizes.

Example of Error:

(chain) Tried to connect invalid block: 0000000000000000012401ef17c6eefc28a25ebc98ac5c085174d5f418ebc3db (478571).
